Embodiment 1

[0052] refer to figure 2 , figure 2 It is the first embodiment of the present invention. In this embodiment, N is 1, that is, the motor driving module group has only one motor driving module, that is, the first motor driving module 40 . The first motor driving module 40 includes a first driver 41 , a first motor 42 and a first linear position encoder 43 . The first driver 41 drives the first motor 42 to rotate, and the first linear position encoder 43 sends the first real-time displacement of the first motor 42 to the counting card 10 . The counting card 10 collects the first real-time displacement, and sends the first real-time displacement to the server 20 , and the server 20 sends the first real-time displacement to the switch 30 . The switch 30 sends the first real-time displacement to the host computer 80 . The upper computer 80 sends the first instruction to the switch 30 according to the first real-time displacement, the switch 30 sends the first instruction to th...

Abstract

The invention discloses a distributed motor driving control system based on TCP / IP network control. The distributed motor driving control system comprises an upper computer, a switch, a server, a motor driving module group and a counting card, wherein the motor driving module group comprises N motor driving modules, and any Nth motor driving module comprises an Nth driver, an Nth motor and an Nth linear position encoder; the Nth driver drives the Nth motor to rotate, the Nth linear position encoder sends the Nth real-time displacement of the Nth motor to the counting card, and the counting card sends the Nth real-time displacement to the upper computer through the server and the switch in sequence; and the upper computer sends an Nth instruction to the switch according to the Nth real-time displacement, the switch sends the Nth instruction to the server, the server enables the Nth instruction to sequentially pass through the first driver to the Nth driver, and the Nth driver controls the Nth motor to rotate according to the Nth instruction. According to the invention, the operation conditions of a plurality of motors can be monitored at the same time, the working efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention is used for the control of laser direct imaging equipment, belongs to the computer field, and in particular relates to a distributed motor drive and control system based on TCP / IP network control. Background technique [0002] In the prior art, a PLC (Programmable Logic Controller, Programmable Logic Controller) can control up to 3 motor drive modules. Since there are multiple working modules in a laser direct imaging device, in order to drive these working modules, it is necessary to use to multiple motor drive modules. If you want to control N (for example, 20) motor drive modules to work at the same time, you need N / 3 PLCs for control. In this way, the cost of equipment procurement is greatly increased, and in order to solve the consistency problem of multiple PLC control, the design scheme becomes complicated. Contents of the invention [0003] The invention discloses a distributed motor drive and control system based on TCP / IP ne...
